Abstract : The GE-225 computer program described herein offers the research scientist and engineer a rapid method of computing coefficients of simple equations that best fit a set of experimental data points when a linear or curvilinear correlation is indicated between the two variables x and y. This linearity can be predetermined from a straight-line plot of these data on either rectangular coordinate, semilog, or log paper. The program also provides statistical information that is useful in appraising how well the line fits the data points, the degree of correlation between x and y, and the confidence interval or limits. Additionally, the program provides information for the analysis of the individual observed data points. (Author)
